Eukaryotic Microorganism
Definition(真核细胞的定义)
Eukaryotic microorganisms have the nuclear membrane coating a cell nucleus, carry out mitosis, and have mitochondria in the cytoplasm. They mainly include yeast (unicelluar fungi), filamentous fungi, microalgae and protozoa. Thus, the eukaryotic microorganisms is not a natural monophyletic taxon. The Fungi is one of the most significant kingdoms in these Eukaryotic microorganisms which have more species.
One of the features that caused taxonomists finally to remove fungi from the plant kingdom was the distinctive chemical nature of the fungal cell wall. Whereas plant and algal cells have walls composed of cellulose, the cell wall of fungi is made up principally of chitin, a strong but flexible polysaccharide that is also found in the exoskeleton of insects.
